EVAPORATOB.

Application :tiled April 9, 1925. Serial No. 21,908.

To all whom it may concern.'

Be it known that I, JOHN F. CLINGIN- SMITH, citizen of the United States, residing at New Castle, in the county ofv Law rence and` State of Pennsylvania., have invented certain new and useful Improvements in Evaporators; and I do declare the following to be a full, clear, and exact description of the invention, such as will en-V able others skilled in the art to which it ippertains to make and use the same. My invention relates more particularly to evaporators used in the formation of opperas (ferrous sulphate), commonly employed in the manufacture of dyes, inks and paints, the object being to rovide a new and improved apparatus for effectively evaporating certain constituents of the acid, leaving the copperas in condition for commercial use.

While the primary intent of the invention is to provide an evaporating apparatus for the purpose set forth or some analogous purpose, the same apparatus may .in some instances be used in connection with blast furnaces for making granulated slag or cinders, but instead of discharging a current of air through a lm of acid, as is done when froming copperas, the apparatus will discharge water under pressure instead of air.

With the foregoing in view, the invention resides in the novel subject matter hereinafter fully described and claimed, the description being supplemented by the accompanying drawing.

Figure 1 is a plan view of the apparatus.

Figure 2 is a vertical sectional view as indicated by line 2 2 of Figure 1.

Figure 3 is a horizontal sectional view on line 3 3 of Figure 2.

Figure 4 is a disassembled perspective view. l

In the drawings above briefly described the numeral 1 designates a main, fluid discharge pipe which is preferably disposed at substantially a horizontal position, said main pipe being provided with a lateral branch -2 or with a plurality of such branches. Each of these branches preferably comprises a bottom 3, a top 4 which declines to the open outer end of the branch, and a pair of vertical sides 5, said sides extending above the top 4 to provide a pair of'upstanding flanges 6 disposed 1ongtudinally ofthe branch 2. These flanges and the top 4 cooperate in forming a trough for discharging the substance to be treated, in a lchin film over the end of the branch 2, so that such film can be acted upon by the fluid discharged from said branch. When forming copperas, air` under pressure is supplied through the main pipe 1 to the branch 2 and consequently discharges from the latter, and the acid to be treated, may well be supplied to the trough, by a valved pipe 7. In the present disclosure, as a plurality of the branches 2 are shown, an equal plurality of the pipes 7 are disclosed, branching from a main pipe 8 which may lead from an acid tank or the like 9. The acid discharged into the trough 4 6, by the pipe 7, runs from the lower end of the trough across the open outer end of the branch pipe 2 in the form of. a film, and the air discharged through this branch pipe, in passing through the film of acid, evaporates the desired quantity of liquid from the latter, leaving the ferrous sulphate or copperas which may be collected in an appropriate receptacle 10. An approriate gate valve 11 is preferably employed or each branch pipe 2, and while any desired mounting can be provided for this gate valve, the construction disclosed may well be followed.

The main pipe 1 is provided with a vertical side 12 whose exterior is formed with a rectangular, flat-sided, shallow recess 13 which opens through the top of said pipe, said side 12 being also formed with a Huid discharge opening 14 which leads to the recess 13 from the interior of the pipe. The branch 2 may be connected with the side 12 of the pipe 1 in any desired manner, along the` vertical and the lower edges of the recess 13, and the inner end of this branch is provided with transverse portions l5, 16 and 17 which are in opposed relation with the flat inner wall 18 of the recess 13. The p0rtion extends along the lower edge of the recess 13 and projects upwardly therefrom, the portions 16 extend along the vertical edges of said recess and project inwardly from these edges, and the portion 17 extends horizontally near the open upper end of the recess 13. In the present showing, these several portions 15, 16 and 17 are formed by the inner ends of the portions 3, 5 and 4 of the branch 2, respectively,and they engage the outer side of the gate 11, to slidably retain the latter in the recess 13.

As above stated, each branch 2 may be connected with 'the main pipe 1 in any desired manner. For illustrative purposes, I have shown it provided with flanges 19 at its inner end, secured by appropriate fasteners 20 to the side 12 of said main pipe.

The apparatus constructed as or substantially as shown and described is very efficient in the formation of copperas for commercial purposesLbut it is by no means restricted to this use. be employed for making granulated slager cinders in blast furnaces, in which instance water will be supplied through the pipe 1, instead of air under pressure. When the device is used for this purpose, melted slagr or cinders will be supplied to the trough 46, by the pipe 7.

As excellent results may be obtained from the eneral construction disclosed it is preferaby followed, however, within the scope of the invention as claimed numerous modications may be made, and in some instances the branch pipe 2 need not necessarily be a branch from a main pipe. but could lead directly from the source of iluid supply.

I claim:

1. A device of the class described comprisn ing a main fluid conducting pipe having-a lateral iluid discharge branch, the latter being provided with an outwardly declined top having upstanding longitudinal ianges co- For instance, it may Wellextensive in length with the discharge branch said top and flanges jointly forming a dat bottomed trough adapted to discharge a substance across the outer end of vthe branch to be acted upon by the dis charged Huid and, means for supplying the substance to be treated to said trough.

2. A device'of the classdescribed -comprisin'g a main fluid conducting pipe having a vertical side formed with a shallow rectangular flat-walled external recess which opens through the top of said pipe, said vertical side having an opening leading to said recess from the interior of the pipe, a lateral branch pipe having its inner end connected to said main pipe at the vertical and loweredges of said recess, said branch pipe having transverse portions extending inwardly beyond said edges of the recess and disposed in opposed parallel relation with the vertical wa l of said recess, said branch pipe having an outwardly declined to provided with upstanding longitudinal anges for the purpose set forth, and a gate slidable vertically in the aforesaid recess and enga ing said transverse portions of the brano pipe.

A In testimony whereof I have hereunto affixed my signature.
